Metal Gear Solid V: Ground Zeroes takes a spot in a montage by PlayStation Japan showing upcoming PlayStation 4 games. Footage of the game can be seen between 0:37 – 0:48. There is actually some new stuff in there as well, albeit only a few seconds. No real spoilers, but it does show some clips of the attack on Mother Base.
And here is a nice GIF from the video, made by user Cartmangus:
